Unveiling the Unique Beauty of the bicolour Teal Saphire
Where lush jungle green meets deep ocean blue in the heart of gamestone
Sapphire is a precious gemstone naturally found in an extraordinary array of colours. Among its rarest and most mesmerising varieties are bicolour sapphires, gems where two distinct hues blend seamlessly within a single crystal.
Of these, the teal sapphire stands out for its exquisite beauty, displaying a delicate and captivating fusion of green and blue reflections. Often compared to the coveted padparadscha sapphire, with its enchanting pink-orange tones, the teal sapphire is gaining recognition for its mysterious allure, extreme rarity, and rising value in the world of fine jewellery.
Geologically speaking, sapphire—like ruby—is a variety of the mineral corundum. Its spectrum of colours results from trace elements present during its formation. In bicolour sapphires, this duality arises from the presence of two or more elements. The teal sapphire’s distinctive green-blue tones are created by traces of iron and titanium within the crystal. These exceptional stones are primarily found in Australia, Madagascar, Montana (USA), and the storied island of Sri Lanka, home to some of the finest examples ever unearthed.
The term teal, referring to a deep blue-green shade, derives from the iridescent plumage of the Eurasian teal bird. This colour has long been revered in Eastern cultures, symbolising harmony, spirituality, and paradise. In Ancient Egypt, it represented eternal life and resurrection, as the meeting point of green (life) and blue (divinity). In the West, appreciation for this hue has grown more recently, tied to a desire for uniqueness and refined distinction.

Every bicolour sapphire is entirely unique and wonderfully unpredictable. The teal sapphire’s mesmerising gradient of green and blue comes alive in shifting light, at times revealing subtle hints of yellow, evoking the rhythm of ocean waves or the gentle rustle of leaves in the breeze.
Other bicolour sapphires may surprise with striking contrasts, such as blue accented with golden yellow, reminiscent of sunlight in a clear sky.
The cut of these gems is vital in enhancing their natural brilliance and the subtle harmony of their hues.
The extraordinary character of these sapphires has made them some of the most sought-after gems among collectors and jewellery connoisseurs today. Their exclusivity and one-of-a-kind beauty make them ideal for bespoke creations with a unique identity, such as engagement rings. Beyond their aesthetic appeal, they have also emerged as an exceptional investment, with demand and market value steadily increasing in recent years.
